Windows 7: Adding USB 3.0 to a Gigabyte GA-EP35-DS3P MoBo Machine

HWiNFO64@Gigabyte_EP35-DS3P System Summary

Thank you all for your contributions.

Out of an abundance of caution I downloaded HWiNFO64 as suggested by JOHNHOH. I have uploaded images of the results. I believe that the _2.jpg image contains the PCIe information and that it says "PCIe v1.1 x 16."

My aging cranium balks at trying to grasp the details, just as I could not follow all the information in the link JOHNHOH provided:

USB 3.0 Speed on PCIe 2.0 x1 Slot | Tom's Hardware Forum

At one point Thermaltake provided both SATA and USB connections with their BlacX Duet. I have one and I was 'disappointed' to discover that only one of the two connectors is seen by my computer. Perhaps it is not connected to the proper SATA port on the motherboard?

I got a newer one and realized when it arrived that it only supports USB 3.x, no SATA.

What other information do I need to supply to better understand what I am up against.

thanks,
baumgrenze

what you posted there is your video card. You need to go to the motherboard section. I'll post a screenshot.
My video card, like yours, shows pci-e 1.1 but that's because its in a low power state and it ramps up only when needed. Not a concern.

Thanks johnhoh,

Now I see how much more info is available.

It is late, I will come back with more detail another day.

thanks

Thanks again,

I've attached a snip of the HWiNFO motherboard section. I can't interpret it. It seems to record only the 2 slots that are in use.

For good measure there are also snips from the manual that might be informative.

The SATA bracket allows 2 external SATA devices to be attached neatly to the system. The cords 'occupy the space' allotted to one of the short PCIE sockets and also allow the video card some air-flow. There is still plenty of room available to install other PCIE and PCI cards.

Perhaps the block diagram will reveal to an expert what level of PCI service the motherboard provides?

thanks

I do not see a pci version there. It looks like you have posted the output from speccy, not hwinfo64. Can you post a screenshot like I did in post #12?

My Apologies

Thanks for your amazingly prompt reply.

Sorry, I hit the wrong quick-launch button and was not attentive to what opened.

Here is the correct image:

You've got pci-e 1.1 there. Earlier I had said that P35 was 2.0 but I see now that was from an article that was later corrected to 1.1. So you have pci-e 1.1 and USB 2.0.

The speed of your drive will be the slowest part of the whole path which as Megahertz said earlier, is very likely to be your hard drive, not the usb or sata or pci-e pathway it uses. To keep it simple lets convert everything into mbps. Not gbps, not MBps, not GBps (the last two are bytes)

USB 2.0 480mbps
USB 3.0 5000mbps
pci 1.1 2500mbps
pci 2.0 5000mbps
sata 2.0 3000mbps
esata 2.0 3000mbps
7200rpm hard drive 700mbps
SSD hard drive 4000+mbps

So that says if you are using a 7200rpm drive, your best option (if you do not have an eSata port) is a usb3.0 pci-e card running in your pci-e V1.1 slot, which is just as fast as if you had a pci-e 2.0 slot, since the hard drive is the limiting factor in either case.

You said earlier you had an eSata port on the motherboard. If that is true, use that. But the specs I saw for your board showed no eSata.

To answer an earlier question. USB 2 is known as USB High Speed, and USB 3 is known as Superspeed. Yes their cables are different. The visible connectors for USB 3 are blue, they are black for USB 2. If you use a black-ended USB cable you will be limited to USB 2 speeds. So if you get a pci-e USB 3 card, you should get a blue-ended USB 3 cable too.
